Emissions Ledger Posts 37.4 38.6 Gt — Largest Single Revision in a Decade
The Global Carbon Project's annual ledger, released at half past midnight Geneva time, revised 2025 fossil emissions upward by 1.2 Gt. Auditors cite previously unreported flaring in the Permian, Bakken, and West Siberian basins, alongside underreported cement production across three South Asian states.
The figure, larger than the entire annual emissions of Germany, lands in the middle of the Eighth Conference of the Parties Working Session and is expected to dominate the closing communique. Chief auditor Yann Bouchard, addressing reporters in a brief tenement on the Quai Wilson, called the revision "the price of three years of unverified self-reporting."
"We have, for the first time, a fully reconciled ledger," Bouchard said. "It tells us that the world is roughly twelve months further along the warming curve than the official record had it."

The atmospheric concentration at Mauna Loa, recorded at 06:00 UTC, stood at 426.18 ppm — the first reading north of 426 in the instrumental record.
